我非常喜欢命令行解析器库(http://commandline.codeplex.com/)。它有一个非常简单和优雅的方式来通过属性设置参数:

class Options
{
    [Option("i", "input", Required = true, HelpText = "Input file to read.")]
    public string InputFile { get; set; }

    [Option(null, "length", HelpText = "The maximum number of bytes to process.")]
    public int MaximumLenght { get; set; }

    [Option("v", null, HelpText = "Print details during execution.")]
    public bool Verbose { get; set; }

    [HelpOption(HelpText = "Display this help screen.")]
    public string GetUsage()
    {
        var usage = new StringBuilder();
        usage.AppendLine("Quickstart Application 1.0");
        usage.AppendLine("Read user manual for usage instructions...");
        return usage.ToString();
    }
}

Powershell Commandlets。

powershell根据命令行中指定的属性进行解析，支持验证、参数集、流水线、错误报告、帮助，最好的是返回。net对象供其他命令行使用。

我发现了一些有用的入门链接:

快速入门教程 MSDN编程指南 MSDN上的Namespace引用

这个问题有很多解决方案。为了完整性和提供替代方案，如果有人需要，我在我的谷歌代码库中添加了两个有用的类的答案。

第一个是ArgumentList，它只负责解析命令行参数。它收集由开关'/x:y'或'-x=y'定义的名值对，还收集'未命名'条目列表。它的基本用法在这里讨论，查看类在这里。

第二部分是CommandInterpreter，它从. net类中创建一个功能齐全的命令行应用程序。举个例子:

using CSharpTest.Net.Commands;
static class Program
{
    static void Main(string[] args)
    {
        new CommandInterpreter(new Commands()).Run(args);
    }
    //example ‘Commands’ class:
    class Commands
    {
        public int SomeValue { get; set; }
        public void DoSomething(string svalue, int ivalue)
        { ... }

使用上面的示例代码，您可以运行以下代码:

exe DoSomething“字符串值

——或——

Program.exe dosomething /ivalue=5 -svalue:"字符串值"

它就是这么简单，也有你想要的那么复杂。您可以查看源代码、查看帮助或下载二进制文件。

请使用apache commons cli API的。net端口。这很有效。

http://sourceforge.net/projects/dotnetcli/

以及用于概念和介绍的原始API

http://commons.apache.org/cli/

我强烈建议使用NDesk。选项(文档)和/或Mono。选项(相同的API，不同的名称空间)。文档中的一个例子:

bool show_help = false;
List<string> names = new List<string> ();
int repeat = 1;

var p = new OptionSet () {
    { "n|name=", "the {NAME} of someone to greet.",
       v => names.Add (v) },
    { "r|repeat=", 
       "the number of {TIMES} to repeat the greeting.\n" + 
          "this must be an integer.",
        (int v) => repeat = v },
    { "v", "increase debug message verbosity",
       v => { if (v != null) ++verbosity; } },
    { "h|help",  "show this message and exit", 
       v => show_help = v != null },
};

List<string> extra;
try {
    extra = p.Parse (args);
}
catch (OptionException e) {
    Console.Write ("greet: ");
    Console.WriteLine (e.Message);
    Console.WriteLine ("Try `greet --help' for more information.");
    return;
}

我最近遇到了FubuCore命令行解析实现，我真的很喜欢它，原因是:

it's easy to use - although I couldn't find a documentation for it, the FubuCore solution also provides a project containing a nice set of Unit Tests that speak more about the functionality than any documentation could it has a nice object oriented design, no code repetition or other such things that I used to have in my command line parsing apps it's declarative: you basically write classes for the Commands and sets of parameters and decorate them with attributes to set various options (e.g. name, description, mandatory/optional) the library even prints a nice Usage Graph, based on these definitions

下面是一个简单的例子说明如何使用它。为了说明用法，我写了一个简单的实用程序，它有两个命令: - add(将一个对象添加到列表中-一个对象由一个名称(字符串)，值(int)和一个布尔标志组成) - list(列出当前添加的所有对象)

首先，我为'add'命令写了一个Command类:

[Usage("add", "Adds an object to the list")]
[CommandDescription("Add object", Name = "add")]
public class AddCommand : FubuCommand<CommandInput>
{
    public override bool Execute(CommandInput input)
    {
        State.Objects.Add(input); // add the new object to an in-memory collection

        return true;
    }
}

这个命令接受一个commandput实例作为参数，所以我下面定义它:

public class CommandInput
{
    [RequiredUsage("add"), Description("The name of the object to add")]
    public string ObjectName { get; set; }

    [ValidUsage("add")]
    [Description("The value of the object to add")]
    public int ObjectValue { get; set; }

    [Description("Multiply the value by -1")]
    [ValidUsage("add")]
    [FlagAlias("nv")]
    public bool NegateValueFlag { get; set; }
}

下一个命令是'list'，实现如下:

[Usage("list", "List the objects we have so far")]
[CommandDescription("List objects", Name = "list")]
public class ListCommand : FubuCommand<NullInput>
{
    public override bool Execute(NullInput input)
    {
        State.Objects.ForEach(Console.WriteLine);

        return false;
    }
}

'list'命令不带参数，所以我定义了一个NullInput类:

public class NullInput { }

现在剩下的就是在Main()方法中把它连接起来，就像这样:

    static void Main(string[] args)
    {
        var factory = new CommandFactory();
        factory.RegisterCommands(typeof(Program).Assembly);

        var executor = new CommandExecutor(factory);

        executor.Execute(args);
    }

程序按预期工作，在任何命令无效的情况下打印正确用法的提示:

  ------------------------
    Available commands:
  ------------------------
     add -> Add object
    list -> List objects
  ------------------------

下面是'add'命令的用法示例:

Usages for 'add' (Add object)
  add <objectname> [-nv]

  -------------------------------------------------
    Arguments
  -------------------------------------------------
     objectname -> The name of the object to add
    objectvalue -> The value of the object to add
  -------------------------------------------------

  -------------------------------------
    Flags
  -------------------------------------
    [-nv] -> Multiply the value by -1
  -------------------------------------
